Description

Technical Field

[0001] The invention relates to the technical field of bridge structures, and in particular to a steel-concrete composite beam connection assembly and an installation method thereof. Background Art

[0002] In high-rise buildings, steel-concrete composite beams can serve as the main load-bearing components of the floor system, bearing the floor load and transferring it to vertical components such as columns and walls. The installation methods of steel-concrete composite beam connection components mainly include welding connection, bolt connection and shear connector connection. Bolt connection and shear connector may be affected by environmental factors such as moisture and corrosion during use, causing rust on the connection components and affecting the strength and reliability of the connection. The connection components need to be inspected and maintained regularly, and any rust should be dealt with in a timely manner.

[0003] In the patent document with the publication number CN113550445A, a longitudinal connection structure of a steel beam, a steel-concrete composite beam and a construction method are disclosed. Through the longitudinal connection structure of the upper flange of the steel beam, one end of the fixed connecting piece is passed through the first mounting hole and the second mounting hole to fix two adjacent steel beams, and the other end extends out of the first mounting hole and extends into the concrete, and an additional nut is screwed on the end to enhance the shear and pull-out resistance between the concrete and the steel beam, ensuring that the connection and force between the steel beam and the concrete meet the requirements.

[0004] When the above device is in use, the fixed connector is used to improve the stability of the steel beam. However, since the main body of the steel-concrete composite beam is concrete, it is easy to cause relative displacement with the steel beam due to the influence of thermal expansion and contraction, which makes the threaded connection of the steel beam easy to loosen, and air can easily enter the connection between the two, causing aging of the thread and affecting the overall installation quality of the steel beam. At the same time, excessive expansion of concrete will cause a certain gap between the steel beam and the steel beam, accelerating the collapse of concrete, which is not conducive to the safety of concrete.

[0005] Therefore, the present application proposes a steel-concrete composite beam connection assembly and an installation method thereof. Summary of the invention

DETAILED DESCRIPTION

[0038] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] like Figure 1-Figure 4 As shown, a steel-concrete composite beam connection assembly proposed by the present invention includes a beam assembly assembly 3, the beam assembly assembly 3 includes a flange 301 and two transverse plates 306 installed on the upper and lower sides of the flange 301, and a positioning anti-environmental assembly 4 is installed on the outer side of the beam assembly assembly 3 for corresponding support according to the thermal expansion and contraction state of concrete;

[0040] The concrete component 1 includes concrete 102, which is fixedly installed directly above the flange 301. Two groups of non-penetrating double-bolt positioning holes 103 are opened on the outer side of the concrete 102. The concrete 102 is opened with corresponding rotating holes 101 between the two groups of double-bolt positioning holes 103. The corresponding rotating holes 101 and the double-bolt positioning holes 103 will be covered by concrete later to achieve complete installation.

[0041] like Figure 1-Figure 5As shown, a torsion positioning column 204 is fixedly connected to the inside of the corresponding rotating hole 101, and an auxiliary spring 206 is attached to the outside of the torsion positioning column 204. When the auxiliary spring 206 is in a state of thermal expansion or contraction of the concrete 102, the internal air pressure drives the auxiliary spring 206 to move accordingly, so that the torsion positioning column 204 is always attached to the auxiliary spring 206. Two limit blocks 205 for limiting the rotation position of the torsion positioning column 204 are fixedly connected to the inner wall of the auxiliary spring 206. The beam stress conduction component 2 includes a first threaded column 207 and a second threaded column 208 fixedly installed in the two double-bolt positioning holes 103. The bottom of the first threaded column 207 is threadedly connected to the beam stress conduction plate 201, and the second threaded column 208 is threadedly connected to the top of the beam stress conduction plate 201. There is a height difference between the installation height of the first threaded column 207 and the second threaded column 208 on the beam stress conduction plate 201. When the concrete is slightly deformed by external pressure or deformed by thermal expansion and contraction, the first threaded column 207 for pressure conduction located on the upper left side of the beam stress conduction plate 201 and the second threaded column 208 for pressure conduction located on the lower right side of the beam stress conduction plate 201 can both conduct the relative torsional force received by the upper and lower positions on both sides to the torsion positioning column 204. When the corresponding rotary hole 101 drives the torsion positioning column 204 to undergo relative torsion, the auxiliary spring 206 rotates to the limit block 205, and the limit block 205 generates a relative spring torsion, thereby buffering the external pressure and causing the concrete or steel beam to undergo thermal expansion and contraction within a controllable range, thereby extending the life and stability of the steel beam concrete structure.

[0042] A second steel bar mounting hole 203 and a first steel bar mounting hole 202 arranged in a height difference state are provided on one side of the crossbeam stress conduction plate 201, a first conduction groove is provided on one side of the second steel bar mounting hole 203 of the crossbeam stress conduction plate 201, and a second conduction groove is provided on one side of the first steel bar mounting hole 202 of the crossbeam stress conduction plate 201. The staff first inserts the first steel bar along the two groups of second steel bar mounting holes 203 and the first steel bar mounting holes 202 for fixation, and installs the second steel bar in the first conduction groove and the second conduction groove, so that when the concrete shakes relatively, the force on the upper right side of the steel beam and the force on the lower left side are transmitted to the vertical steel beam block 305, reducing the external pressure on the concrete, thereby utilizing the supporting force of the steel beam to improve the stability of the entire concrete.

[0043] like Figure 1-Figure 8As shown, the interior of the horizontal plate 306 located below the flange 301 is provided with a lower built-in thread 403 connected to the flange 301, and the lower built-in thread 403 and the upper built-in thread 402 are arranged equidistantly, two groups of positioning anti-environmental components 4, one group of positioning anti-environmental components 4 is connected to the upper built-in thread 402, and the other group of positioning anti-environmental components 4 is connected to the lower built-in thread 403, so as to improve the sealing performance of the connection between the horizontal plate 306 and the flange 301, and avoid airflow causing accelerated aging of the thread groove. The beam assembly 3 also includes The flange 301 and the cross plate 306 are provided with multiple bolts 303 threadedly installed inside. The outer side of the flange 301 is threadedly connected with multiple shear connectors 302, and the multiple shear connectors 302 are arranged in equal proportion with respect to the surface of the flange 301. A vertical steel beam block 305 is fixedly installed on one side of the flange 301. The number of positioning anti-environmental components 4 that can achieve effective connection between the flange 301 and the concrete component 1 at the joint is set as required to make up for the defect that the shear connector 302 is not set here and the force transmission does not meet the requirements. In order to ensure the connection force requirements of the two adjacent flanges 301, bolts 303 are also set on the cross plate 306 and the flange 301.

[0044] In this embodiment, Figure 6-Figure 9 As shown, a corresponding mounting ring 304 is welded to the outer side of the horizontal plate 306, and the corresponding mounting ring 304 is connected to the flange 301;

[0045] The positioning anti-environmental component 4 includes an upper built-in thread 402 provided on the inner wall of the corresponding mounting ring 304 and the flange 301, the inner thread of the upper built-in thread 402 is connected with a hollow threaded slide rod 404, the inner wall of the corresponding mounting ring 304 is slidably connected with a hollow screw 401 through a slide rail, the outer side of the hollow threaded slide rod 404 is threadedly connected to the inner wall of the hollow screw 401 through a threaded slideway 405, the outer side of the threaded slideway 405 is slidably connected with a positioning cylinder 409, the outer side of the positioning cylinder 409 is fixedly connected with an annular push block 407, the annular push block 407 is fixedly installed at the bottom of the hollow screw 401, and a side of the annular push block 407 away from the positioning cylinder 409 is fixedly connected with a plurality of card The inner wall of the corresponding mounting ring 304 is fixedly connected with a sealing airbag block 406, and the sealing airbag block 406 is fixedly connected with a hollow pressure ring 411 on the side facing the annular push block 407. The surface of the hollow pressure ring 411 is provided with a plurality of arc-shaped limit grooves 410 for preventing the locking cylinder 412 from sliding outward. The corresponding mounting ring 304 is located above the upper built-in thread 402 and is fixedly connected with a limited stopper 408. During the initial installation, the worker threadedly connects the hollow screw 401 and the hollow threaded slide rod 404 in the flange 301 and the corresponding mounting ring 304. The diameter of the annular push block 407 is larger than the normal inner diameter of the hollow pressure ring 411 and the sealing airbag block 406, and the annular push block 4 07 slides into the lower part of the inner wall of the arc-shaped limiting groove 410. As the annular push block 407 is inserted into the corresponding mounting ring 304, the hollow pressure ring 411 and the sealing airbag block 406 are pressed against the inner wall of the corresponding mounting ring 304, thereby improving the sealing between the hollow threaded sliding rod 404 and the corresponding mounting ring 304, preventing external air from entering the threaded area and causing aging of the threaded area. At the same time, when the concrete component 1 is in a thermal expansion state, the concrete component 1 is heated and expands outward as a whole, and the hollow screw 401 wrapped therein also expands outward synchronously, and the arc-shaped inner wall of the arc-shaped limiting groove 410 generates resistance to the engaging cylinder 412, thereby reducing the outward movement range of the hollow screw 401, and also reducing the concrete The thermal expansion degree is reduced, and the gap between the hollow screw 401 and the threaded area and the concrete is reduced to prevent aging of the steel beam connection. When the concrete component 1 is in a cold shrinkage state, the concrete component 1 shrinks inward as a whole, and the hollow screw 401 is squeezed downward by pressure. In addition to squeezing the sealing airbag block 406 to improve the sealing performance, the annular push block 407 also squeezes the sealing airbag block 406. At the same time, when the hollow threaded slide rod 404 moves downward along the slide rail of the corresponding mounting ring 304, the positioning cylinder 409 contacts the thread of the hollow threaded slide rod 404. The sliding friction between the two causes the hollow threaded slide rod 404 to continue to rotate and connect more closely with the upper built-in thread 402, thereby improving the stability of the steel beam in the cold shrinkage state and preventing the steel beam connection from loosening.
